If you search eur to usd on Google, you'll see a chart.

The chart starts from 198x as below:

However, on this Wikipedia page. It says

The euro came into existence on 1 January 1999

Is it a Google mistake? What does the data before 1999 mean?

The same wiki page says EUR replaced ECU with 1:1 rate. So history before 1999 likely represents ECU/USD rate.

However, I'm not sure why is starts in 1982 then, as ECU was introduced in 1979.

    Looks like all their data goes back to 16 Apr 1982, e.g. GBP/USD has the same starting point. Commented Apr 10, 2022 at 18:31
